MACHINE FOR REDUCING AND BAKING CEREALS IN FORlVll.

SPECIFICATION forming part of Letters Patent NO. 625,696, dated May 23,1899.

Application filed March 2, 1898- Serial No. 672,293. (No model.)

To all whom it may concern:

Be it known that I, HENRY D. PERKY, a citizen of the United States, anda resident of Worcester, in the county of Worcester and StateofMassachusetts, have invented certain new and useful Improvements inMachines for Reducing and Baking Cereals in Form; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference beinghad to the accompanying drawings,and to letters of reference marked thereon, which form a part ofthisspecification.

Figure 1 of the drawings isa sectional elevation showing the mechanismembodying the invention. Fig. 2 is an end view of one of thereducing-machines, showing one form of means for separating the layers.Fig. 3 is a similar view showing another form of such means. Fig. 4 is adetail sectional view of a portion of one of the reducing-machines, andFig. 5 is a plan View of a part of the reducing-rolls.

The object of the present invention is to provide means for reducingcereals from the grain or berry form to continuous layers of shred orthread-like form and dividing and baking the same in large quantitiesfor commercial use. Wafers of thin and lighter character can be made,which are designed to serve admirably for lunch purposes, teas, andespecially for food for invalids.

In the accompanying drawings the letter A designates thereducing-machine, having a pairof reducing-rolls of the generalcharacter set forth in Letters Patent No. 502,378, dated August 1, 1893,into the hopper A. of which the grain, having been properly boiled andsalted and dried, is fed and from which it is discharged in the form ofcontinuous threads or shreds, which fall into an irregular layer uponthe traveling receiver B, which may also provide the baking-surface.

UsuallyI prefer to employ several red ucin gmachines in line with eachother in order that the continuous discharge may consist of severallayers, which, falling upon the traveling receiver B in succession,increase the thickness of the ribbon and give it more regularity ofstructure.

leys H H and the supporting-rollers 7.0.

If the rolls employed in the reducing-machines are of sufiicient lengthto produce a ribbon which is too broad, dividing-partitions C, extendinglongitudinally,inay be employed to' separate the layers into narrowparallel strips, (see Fig. 2,) or the division. may be effected by meansof partition-surfaces, as indicated at cl, Fig. 5, on the grooved rollD, or it may be cut by dividers D as indicatedin Figs. 3 ande. From thereceiver-belt the layers fall upon the traveling baking-surface e of theoven F. 4

G indicates a rotary cutter or marker, whereby the layers or strips ofthe product are designed to be transversely indented or divided intolengths of suitable proportion.

E represents the carrying-baker, which receives the product from thereceiver B and which may consist of an inside heated roller or drum oflarge diameter, but is preferably, as shown, a traveling band of sheetiron or steel having the driving and adjusting pul- Between the upper orfeed branch of this band and its lower branch is arranged a gas-jetheater 1, which is preferably adapted to heat boththe upper and lowerbranches of the band, or the band may be arranged to pass overelectrically-heated material.

J designates the top baker, which may be stationary and may consist of aplate heated by electricity, or gas-jets may be employed; but in orderto insure the top cooking and to give more uniform appearance to thewafers I prefer to employ a traveling band of similar character to thecarrying-baker E. This band'maybe run upon the edge guides l and isdesigned when it is to be in contact with the upper surfaces of thewafers to have the same speed as that of the carrying-band. The band Jmay also serve to level somewhat the upper surfaces of the wafers. Theoven is incased and provided with the proper draft and with suitableopenings X, with doors along the sides to permit inspection of andattention to the work. The wafers discharged over the inclined chute Zare designed to be light and crisp. They readily break apart in lengthsat the indentations and can be easily and conveniently packed in casesof suitable character.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an oven, the combination with an endless metallic carrying andbaking band, of a second endless band above the first, and designed totravel at the same rate of speed, said second hand having a portion ofits length adjacent to a portion of the first-named band and designed tocontact with the material carried by the latter, together with means forheating said bands, substantially as specified.

2. The combination with an oven-closure having a low rearward extension,open at its upper portion, and having a discharge-chute at its oppositeend'portion, of an endless horizontal metallic carrying and baking bandin.

said closure, and means for forming the product to be baked and forautomatically delivering the same onto the said band at the open portionof the said closure, substantially as specified.

3. The combination with an oven-closure having a low rearward extension,open at its upper portion, of an endless metallic carrying and bakingband in the said closure, means for forming the product to be baked andfor automatically delivering it onto the said band at the open portionof the said closure, and a device working through said open portion forsevering the product after it has been delivered onto the said band,substantially as specified.

4.. The combination with an oven-closure having an opening at each end,of a horizontal endless metallic baking-band in the said closure, ahorizontal baking and leveling band within said closure, and having aportion of its length adjacent to the upper portion of the first-namedband, and in position to contact with the material carried by thelatter, and gas-jets directed against or adjacent to the non-bakingsurfaces of the said bands, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

HENRY D. PERKY.
